HLN467W Samsung DLP

My 3 year old samsung was just turning off usually in the beginning and I would have to reboot to work.
This has been going on for a while and I put up with it.
Last night the screen went to black and white with a strobe effect and a
loud fan type noise.Tv will not come on.
The read out on front sez lamp and temp.
Does the bulb need replacing,does it show burned out because mine looks like new and the bulb fan was not running as I looked at inside of TV.
Any suggestions.
ALSO i have a small 2 inch shadow over the bottom left corner of the screen and you can see through it a little
Please let me know.

I have been all over the internet and have decided it is either 1) bulb 2) Ballast or 3) Color wheel.

I know it could be a board or a light engine.

I am looking for more information to detail what exactly I need to replace.

The bulb issue I need to know if mine is bad.

Usually if a bulb is bad it goes out totally, but mine has not.

Please can you be more specific.

Thanks you for your help.I realize there are only 2 moving parts in the TV.
Cooling fan and Color Wheel.

The blink code you see on the front should indicate what the TV thinks is the problem. If the fan has stopped, the set will shutdown. Lamp failures will not necessarily be visible by looking at the lamp. Check the owner's manual for the LED indicator code and check whatever it indicates. Try a new lamp as bad lamps can cause all kinds of odd behavior. Report back with what you find. In the meantime, I'll look up your model to see if there are any common problems/solutions.

Check the color wheel as it is the most common problem when it comes to noise from DLP's.To see if it is - Turn on the set.When the noise starts, turn off the set. If the noise goes away within 5 seconds, then the color wheel is faulty. If the noise goes away after one to one and a half minutes after the set was shut off, then it will be one of the fans making the noise.

Check the motor that is making the noise. Especially check any capacitors that relate to the drive motor. It is not uncommon for mechanical failures of solder joints to cause motor problems.

The "shadow" you note, may be connected to this, but should be easier to spot when opened.Check the motor that is making the noise. Especially check any capacitors that relate to the drive motor. It is not uncommon for mechanical failures of solder joints to cause motor problems.

I had the same issue about a year ago and they replaced the power supply on the unit. Just started doing the same thing again now on my end as well. 1 more repair after this and I can lemon law it on the warranty that I took out on it.

Working on the same problem. My neighbor and I have the same model of Samsung DLP TV. After 3 years, his begin to turn off after a short period of use. He replaced the lamp, but the problem continued. He took it to a repar shop and they said circuit board, yada yada yada, 800 bucks. He bought a new TV for a grand. I have his old TV in my garage for parts, and low and behold, out in the garage where it is cooler and the TV is not in a cabinet, it works just fine. I think the problem is one of overheating. My suggestion is to move the TV to a place where is has plenty of air circulation and see what happens.
